Cone wrenches, some homemade (Sturmey Archer and Bendix hubs)
Spoke wrench
Spoke wrench that works
Truing stand, homemade
Various spline tools (bb, freewheel, etc.) over the years
Chain tool
Tire levers
Pedal wrench
Old fashioned bottom bracket tool
Repair stand, a birthday gift from my spouse

All of these were purchased as needed over the span of 30+ years. I don't buy any specialized tool until I need it. If I have to wait, I ride another bike.
